OUTCOME
By the end of the lesson you will be able to describe and apply Newton's first Law
We are subjected to forces everyday, Newton explained that objects will not accelerate unless there is an overall force acting, other wise they remain at rest OR constant speed
In a world without air, mass really does not count
LEARNING TASKS
Explain
Use a mind map to explain the terms force due to gravity, friction, normal, compression and tension force
There is a book on a table. Why doesn't the book fall?
Explore and Elaborate
Prac: Constant velocity ice
activity
Prac: Constant velocity with balanced forces
Evaluate
Try the text questions
